Support the storage of GraphQL aggregate analytics
MDCB (Multi-Data Center Bridge) has been enhanced to support the storage of GraphQL aggregate analytics directly. This allows for better tracking and analysis of GraphQL usage across distributed environments when Gateway send analytics data directly to MDCB, which processes and sends the data to the analytics storage. This enhancement simplifies the storage and management of GraphQL analytics without Tyk Pump, improving efficiency and ease of use.

Deprecations
There are no deprecations in this release, however with the introduction of new healthcheck endpoints we encourage customers to start using the new /liveness and /readiness endpoints and avoid using the old /health endpoint.
Recommendations for users:
- Migrate to new health check endpoints in order to get more detailed information. For Kubernetes users, use Helm Charts v1.6 to upgrade MDCB to set liveness and readiness probes of MDCB deployment to the new health check endpoints.
Upgrade instructions
If you are using a 2.6.x version, we advise you to upgrade ASAP to this latest release. If you are on an older version, you should skip 2.6.0 and upgrade directly to this release.
Release Highlights
New Health check probes
Two new health check endpoints have been added to improve monitoring and diagnostics:
/liveness: This endpoint provides a quick check to determine if the MDCB application is alive and running./readiness: This endpoint offers a detailed status of components and dependencies required for MDCB to serve traffic. It includes status checks for:- Database connectivity
- Redis connectivity
- RPC server status
These new endpoints allow for more granular monitoring of MDCB’s operational status, enabling quicker identification and resolution of potential issues.
New Configuration Access Endpoint
Two new /config and /env endpoints have been implemented, allowing developers to access the current configuration state of the MDCB instance in real-time. This feature provides:
- Secure access to configuration data
- Automatic redaction of sensitive information
- Up-to-date view of the running configuration
This addition enhances debugging capabilities and provides valuable insights into the MDCB instance’s current settings.
Please refer to the changelog below.

Changelog
Added
-
Added `/liveness` endpoint for quick checks on MDCB application status
Added `/liveness` endpoint that reports if MDCB is running. It returns status 200 if MDCB is alive. It returns status 503 if MDCB is not operational. In that case, a restart is recommended. -
Implemented `/readiness` endpoint to detail status of critical components and dependencies
Added `/readiness` endpoint that reports if MDCB is ready to serve request. It returns status 200 if MDCB is ready. It returns status 503 if MDCB or one of the dependencies is not ready. -
Introduced `/config` endpoint for secure, real-time access to MDCB instance configuration
Added `/config` endpoint that returns MDCB instance configuration in JSON format. It requires an administrative key provided in the `x-tyk-authorization` header for access, ensuring secure and controlled usage. Successful requests return MDCB JSON configurations with passwords and sensitive information redacted. -
Introduced `/env` endpoint for secure, real-time access to MDCB instance configuration
Added `/env` endpoint that returns MDCB instance configuration as a list of environment variable keys and values. It requires an administrative key provided in the `x-tyk-authorization` header for access, ensuring secure and controlled usage. Successful requests returns a list of environment variable keys and values with passwords and sensitive information redacted.
